I would like to buy a new monitor. I have looked all over the Internet and have, more or less, baffled myself.
I currently have the monitor that I got with my PC but that only has a maximum resolution of 1440x900. As I do a lot of photography I would like something a little better. I have looked at Iiyama, BenQ etc., etc.
Iiyama seem to cater for the very cheap or very expensive and the same seems to apply to BenQ. I have also been warned off of TN panels, not that I know what they are ! It seems that an IPS panel is the one to go for ?
It seems that a lot of the screens have a resolution of 1680x1050. Armed with this info I picked out a BenQ screen, FP222WH, and asked a boffin at work what his thoughts were. Sadly he said that for a 22" screen I should be looking at a higher resolution.
Any suggestions would be much appreciated.
Thank you.
